CAR-ROOF.

Specification of Letters Patent.

Patented Feb. 13, 191?.

Application filed August 23, 1915. Serial no. 46,880.

To all whom it may concern:

Be it known that I, JOHN MCMULLEN, a citizen of the United States, residing in Bufialo, in the county of Erie and State of New York, have invented a new and useful Improvement in Car-Roofs, of which the following is a specification.

My invention relates to inside car roofs of the Winslow type, and has for its objects to improve the construction of such roofs, so that the seam cap straddles and overhangs the super-purlins, and the latter are bolted to the super-carlines without perforation of the cap, and also bolted, if desired, through the carlines and purlins. This greatly strengthens the construction, and secures perfect water-tightness around the through bolts. Further advantages, in the holding of the roof sheets by the said seam caps, and in the application of the top wooden sheathing, are also attained.

The invention consists in the parts and combinations thereof hereinafter set forth and claimed. 7

In order to make the invention more clearly understood I have shown in the accompanying drawings means for carrying the same into practical eflec-t, without limiting my improvements, in their useful applications, to the particular construction which, for the purpose of example, has been made the subject of illustration.

In the said drawings Figure 1 is a plan view of a portion of a car roof embodying the invention, parts of the same being broken away.

Fig. 2 is a side view of the same.

Fig. 3 is a vertical cross section of the game, on a larger scale, on line IIII II of ig. 1. v

Fig. 4 is a similar section, on a still larger scale, showing the eaves portion of the roof.

Fig. 5 is a plan view of the end seam cap.

Figs. 6 and 7 show respectively a side view and a plan of the intermediate seam ca Y I Fig. 8 is a vertical section across the end super-carline and end cap.

Fig. 9 is a section across an intermediate super-carline and seam cap, on line IX-IX of Fig. 1.

Fig. 10 is a perspective view of the intermediate roof sheet.

Figs. 11, 12 and 13 show respectively a plan, an end view and a side view of the said roof sheet.

Referring to the drawings, the frame of the roof comprises side plates 1 and end plates 2 connected therewith, which members are supported by the upright posts and braces (not shown). On the side plates are supported carlines in the form of angle bars havinga horizontal flange 3 and a vertical flange 4. The flange 4 is bent laterally at its end to fit against the inner faces of the side plates, as shown at 5 in Fig. 1, and is bolted thereto. The flange 3 is bent at its ends into inverted U-form at 6 (Figs. 1 and 4) to fit partly around the side plates, and the outer member of the flange ,6 is secured to the side plate by a bolt 7 The carline extends from side plate to side plate, and is hippedat its middle where it supports the ridge pole 8, the latter being secured to the several carlines by bolts 9 which preferably pass down through the saddles 10 of the running board 11.

The ridge pole is formed at each side with a groove 12 adapted to receive the ridge ends of the roof sheets, and is also formed at intervals with the usual recesses 13 above said grooves to receive the ridge ends of the supercarlines and the seam caps, this con struction'being of a known character.

14: indicates the purlins resting on and secured tothe top flanges 3 of the carlines. In the construction illustrated there are two purlins at each side of the roof, but the invention is not dependent upon the particular number of purlins. On said purlins rest the supercarlines 15 having their ridge ends entered in the said recesses 13 and resting at their eaves end upon the side plates. 16 indicates the intermediate roof sheets, formed of sheet metal with vertical side flanges 17 terminating in horizontal flanges or lips 18. The roof sheet is also formed with a depending eaves flange 19 (Fig. 10). The roof sheets are of such width as to substantially fill the space between the superside plates with their depending flanges 19 extending down upon the outer side of an in ner fascia 20. This fascia holds the side sheathing 21 to the side plates and at the outer side of it is arranged an outer fascia 22 which is held away from the inner fascia by spacing washers 23 through which pass 7 the bolts 24 which unite the said parts with the side plates.

Over the super-carlines and flanges 18 of the roof sheet are held the super-purlins 25, the same being preferably in line with and above the 'purlins 14. These super-purlins are at right angles to and may be said to intersect with the supercarlines, and at such intersections the super-'purlins, the

.super-carlines and the purlins are firmly (Figs. 6 and having top plates 27 and depending flanges 28. Where these caps intersect with the super-purlins the top plates are bent upward and the flanges 28 outward to form elevated cap portions 29 parallel with thesuper-purlins and inclosing portions of them where they intersect with and above the super-carlines. The parts 29 thus cover the fastenings 26 and prevent any leakage down along the through bolts, and conse quent rotting of the wooden parts at their intersections between their contacting faces. Over the side plates are arranged supporting strips 30 for the outside tongued and grooved wooden roof 31, and these strips are inclosed where they rest on the super-carlines by elevated cap portions 29, which cover the bolts 32 which secure said strips to the side plates.

The outer ends ofthe seam caps are closed, as by bending down their top plates 27 to form end plates 33, the surplus metal being bent against'the side plates 28 at 3 1, The seam caps are held from movement toward the eaves by their engagement with the super-purlins and the end plates 33 thus hold the roof sheets from similar movement.

But the cap portions 29 are of such formation as to allow of the free outward sliding of the roof sheets when the outer ends of the'se'am caps are a little elevated, as above leakage which may take place through this 7 sheathing is Warded from all of the intersections of wooden parts, and'fro m their fastenings, andruns off from the roof sheets over their eaves flanges 19 and through'the space. between the inner and outer fascia (Fig. 4:).

Itwill be understood that the end roof sheets may be finished at one sidewith a depending flange, in a known manner, in

I place of the seam flanges 17, 18. Over'the end plate'is arranged a strip 35 (Fig. 8)

which may be termed an end super-carline,

of the'end roof sheet with the flanges 17, 18 just as in the case of. the intermediate roof sheets, and to engage theseflanges with the inner side of the strip '35, as seen in Fig. 8. This strip and said flanges of the end roof sheet are inclosed by an end seam cap such as is shown in'Fig. 5, which is formed with and it is preferred to form the terminalside V the elevated seam portions 29 but on the outer side may be straight and flush with the end'of the car without a flange 28. V It will be seen from the foregoing that any water trickling down from the ridge canhave no access to any of'the wooden nation: a roof-supporting frame; flanged metallic, seam caps closed at their eaves ends; metallic roof sheets having upstandwithin the said caps and retained by their closed ends; super-carlines arranged within the side edges of the roof sheetsand within the caps; super-purlins onsaid super-carlines and included within-parts of said seam caps; and an outside board roof inclosing and confining the said caps and "super-purlins; substantially as specified.

1 ing flanges at their sides which are engaged V i 2. In an inside car roof, in-combination:

a roof-supporting frame; super-carlines and intersecting super-purlins on the. frame; roof sheets having side flangesjengaging the super-carlines; seam caps having side flanges, which are interrupted at the super-purlins, inclosing the side flanges of .said

the roof sheets and the super-carlines andi also having elevated portions, where the side flanges are interrupted, inclosing the intersecting portions of the super-purlins; and an outside roof inclosing the seamcaps and super-purlins. 1

3. A combined snper-carline and super.

purlin sheet metal cap for carroofs adapted to inclose the intersection of said. members, the same being bentito form an interrupted top portion and interrupted side flanges adapted to inclose the super-carline, and signature hereto in the presence of two subbent to form an elevated top portionand scribing witnesses. elevated longitudinal flanges adapted to inclose the super-purlin, the said elevated por- 5 tions being extended longitudinally beyond Witnesses:

the said side flanges. T. S. DAVEY, In testimony whereof I have afiixed my W. G. WINTERBERG.
